Anything over 93 octane is a waste, and may actually reduce output slightly.
I am confused if 93 octane even does anything better than 91. The manual recommends 91, but Chevy website 93 octane. Anyone really know or have some ideas here?

And 'ricer' is a little derogatory, and wasn't really a term used back then. You either had a 'hog' or a 'honda'. And that was a little derogatory.

My previous car needed 95 octane to run right. It used to bust my butt blending $4.29/gallon 100 octane in with premium.
Premium at 10 cents / gallon extra is nothing, especially if you can afford a new C6.

The bottom line: to each his own...it won't hurt the car, and I really defy anybody to drive a C6 on midgrade and then on premium and actually be able to TELL the difference in performance. Just my 2 Cents.

With a compression ratio of 10.9:1, even with aluminum heads, the higher the pump gas octane rating the better. Speaking the words regular gas and vette in the same sentence should be covered in the service manual too, under Chevette.

although I believe there would be a difference (which I believe is what you are saying). I'm sure timing will be pulled w/ regularI always feed 'um what the designers call for. My Corvette will get super unleaded (as my C5 did). My Tahoe gets regular (per the owners) manual. My '79 Camaro gets super unleaded due to 9.5:1 CR and an agressive mechanical advance curve.
